请用C++代码实现以下内容：学生成绩处理问题。假定“生物医学工程”和“生物工程”两个专业的学生分别上以下课程： (1) 生物医学工程：数学、英语、物理、电子、机械 (2) 生物工程： 数学、英语、物理、分子、生化 假定“生物医学工程”班有4名学生，“生物工程”班有5名学生，分别计算并输出两个班级各门课程的平均分、最高分、最低分、……。 要求： 采用派生关系建立以下类：abstractClass(抽象类)类、BMEclass(生物医学工程班)类和BEclass(生物工程班)类： (1) 对数据而言， class类：包含两个班级的共同课程； BMEclass类和Beclass类：分别包含各自的课程； (2) 对数据(成绩)的处理函数(含输入输出)，请放置在合适的类中。

这里是一个简单的实现：

在此实现中，我们定义了一个抽象类 `AbstractClass`，其中包含了两个班级的共同课程，即数学、英语和物理。然后，我们创建了两个派生类 `BMEClass` 和 `BEClass`，分别代表生物医学工程班和生物工程班，并添加了各自的课程，分别是电子、机械和分子、生化。

这些类都包含了 `input()` 和 `output()` 函数，用于输入和输出数据。在 `BEClass` 中，我们还添加了一些其他函数，用于计算各门课程的最大值、最小值和平均值。

在 `main()` 函数中，我们首先创建了 `BMEClass` 和 `BEClass` 的对象，并调用它们的 `input()` 和 `output()` 函数来输入和输出数据。接下来，我们使用 `BEClass` 中定义的函数计算各门课程的最大值、最小值和平均值，并将它们输出到控制台。
